Assembler code doesn't get any simpler to use than those.  Just compile 
with GCC,  add #include "lpc_sys.h" in your application to provide the 
appropriate prototype defines and typedefs. Compile and link in with your 
application.

The documentation shows hows they are used.

Basically you do the following

  PROCESSOR_STATUS prev_int;

  prev_int = DisableInterrupts( INTERRUPT_DISABLE_MASK);

do stuff protected from interrupts

  RestoreInterrupts( prev_int);

That will take care of making sure interrupts are disabled and then restore 
them to what they were before you disabled them.
